OpenStudy (anonymous):

Well if not B it's C.

OpenStudy (anonymous):

Its incorrect too my friend,Can I get your working yet again?

OpenStudy (anonymous):

9πx2+48πx+64π

OpenStudy (anonymous):

?

OpenStudy (anonymous):

What is the area of a circle?

OpenStudy (anonymous):

(Pi) times the Radius squared.

OpenStudy (anonymous):

Then can I write it like this? \[\pi (9x^2+ 48x + 64)= \pi (R)^2=>(3x+8)^2\]

OpenStudy (anonymous):

pi gets cancelled on both the sides,and you can convert (9x^2+48x+64) to perfect square, now take sqrt on both sides
